It loses its electric value and becomes chlorine. Part of this chlorine dissolves in the water near the positive electrode 14 as it is, and part of it reacts with water to produce hypochlorous acid or hypochlorite ion, which gives an effective chlorine concentration having a bactericidal action. To be A part of the remaining chlorine is released as hydrochloric acid or chlorine gas. Thus the water in the vicinity of positive electrode 14 is acidic, acidic water containing hypochlorous acid or hypochlorite ions spreads passage of liquid pass through the free positive electrode 14 to the anode compartment B. Further , sodium ions in the salt water in the salt water chamber A enter the cathode chamber C through the diaphragm 12 and the negative electrode 1
It loses its electric value upon contact with 5, and reacts with water in the vicinity of the negative electrode 15 to generate sodium hydroxide and free hydrogen to make the water in the vicinity of the negative electrode 15 alkaline. The alkalinized water spreads in the cathode chamber C through the negative electrode 15 through which the liquid can pass freely. The acidic water and the alkaline water thus generated in the anode chamber B and the cathode chamber C, respectively, are sent out from the acidic water take-out pipe 36 and the alkaline water take-out pipe 37, respectively, and are used for desired purposes.

Due to the different diffusion rates of Na ions and Cl ions in the circulating saline, the pH of the saline in the saline tank 20 gradually changes as the electrolysis proceeds. Therefore , the pH sensor 24 is set to p in the salt water tank 20.
Detecting a H, opening and closing of the acidic water supply valve 38 and an alkaline water supply valve 39 is controlled by the control circuit 50 on the basis of a signal representing the detected pH.

The voltage and current (power consumption) required to obtain electrolyzed water with a concentration within the specified range is greater than the voltage and current (power consumption) required when electrolyzing neutral water , and the burden on the electrodes This is because larger than during electrolysis of but a medium of water.
